M24SR02-YMN6T/2 Application Field and Working Principle

The M24SR02-YMN6T/2 is a dual-interface, dual-protocol contactless Memory IC from STMicroelectronics. It belongs to the category of RFID (Radio-Frequency Identification), RF Access and Monitoring ICs. This IC offers 512-Bytes of EEPROM memory and a secure file system.

Application Field

The M24SR02-YMN6T/2 is designed for applications such as smart cards, NFC-enabled phones, NFC payment systems, transportation tickets, and many other applications that require secure data storage.

It is ideal for mobile payments, loyalty cards, ticketing systems, and authentication/access controls.

Features

• 512-Bytes of EEPROM memory
• Secure file system
• Support for two contactless protocols (ISO/IEC 14443A/B and ISO/IEC 15693)
• Optimized for NFC devices
• Dynamic memory management
• High durability
• Low standby current

Working Principle

The M24SR02-YMN6T/2 operates according to the Card-Select Mode/2-Wire protocol, which enables it to use two bidirectional lines (I2C and RF) for communication. The contactless side and the contact side of the IC can be activated and addressed simultaneously, enabling a fast and secure data exchange between the device and the card.

The M24SR02-YMN6T/2 supports two contactless protocols (ISO/IEC 14443A/B and ISO/IEC 15693). This allows the IC to be used for a wide range of applications, including access control, mobile payments, loyalty cards, and ticketing systems.

The M24SR02-YMN6T/2 also features Dynamic Memory Management (DMM), which allows for an efficient use of the memory. The DMM feature is also used to enable the secure file system on the IC, ensuring that data stored on the IC is secure and cannot be accessed without the correct authentication.

In addition, the M24SR02-YMN6T/2 features a low standby current, which helps to extend battery life and reduce cost of ownership.
